Definitions

  • the present invention relates to systems for providing controlled venting and preventing escape to the atmosphere of fuel vapor from a fuel tank, particularly on board a motor vehicle, and more particularly during refueling.
  • a storage unit typically a remotely located canister charged with charcoal, connected to receive fuel vapor from a float operated vent valve provided on the fuel tank.
  • vapor is adsorbed in the canister and stored.
  • the canister is purged by air and the fuel vapors are drawn from the canister into the engine inlet and comprise a portion of the engine combustion charge.
  • the canister When the engine is not operating, the canister must absorb all of the vapor from the fuel tank which is either displaced from the tank through vent valve by the rising fuel level during refueling, or from the tank when the vapor pressure rises above atmospheric.
  • FIGS. 3 and 4 a known system of the above-described type is illustrated and has the fuel tank 1 with a filler neck 2 receiving fuel during refueling by a filler nozzle 3 inserted into the upper end 2 a of the filler neck through a seal 4 and sufficiently further to open a one-way flapper valve 5 and permit the nozzle to discharge into the filler neck 2 .
  • a pressure relief valve 6 is provided in the filler neck upper end 2 a and serves as a bypass for the seal 4 in the event of a failure of the aspirator controlled automatic shutoff in the refueling nozzle 3 .
  • a float operated vent valve 7 is received through an aperture in the upper wall of the tank and has a flange 8 registering against the exterior of the upper tank wall; and, the valve flange is secured to the upper tank wall.
  • the valve 7 has its outlet connected to a vapor vent conduit 9 which is connected to a storage canister 10 which has an outlet line 11 adapted for connection to an engine air inlet (not shown).
  • the canister 10 has an atmospheric purge air inlet 12 for permitting air to be drawn in the canister upon engine startup and creation of a vacuum in the line 11 . Vacuum in the canister is created by the flow restriction of the granular fill in the canister.
  • Air leakage past the mechanical seal 4 in the tube around the refueling nozzle causes increased vaporization of fuel in the tank and the canister is subjected to increased vapor flow from the tank. This results in the requirement for additional canister capacity.
  • a recirculation line 13 has one end connected to the upper end of filler neck 2 a below the seal 4 .
  • the remaining end of the conduit 13 is connected to the upper wall of the tank 1 and extends to a desired liquid fill level within the tank and is closed by the rising level of the fuel in the tank as indicated generally by reference numeral 14 in FIG. 3.
  • FIGS. 3 and 4 permit fuel vapor to be recirculated through the filler nozzle until the fuel level 14 closes off the end of the tube 13 within the tank. Closure of tube 13 causes continued fuel flow through the nozzle to create a vacuum within upper tube 2 a below seal 4 , which vacuum starves the nozzle aspirator and effects nozzle shutoff.
  • FIG. 5 another system of the prior art is illustrated pictorially where a fuel tank 1 a has a filler tube 4 a with an enlarged cup-shaped upper end portion 5 a shown with refueling nozzle 3 a received therein and having the end thereof inserted in closely fitting arrangement in the upper end of the filler tube 4 a .
  • the lower end of the filler tube 4 a extends into the fuel tank and has a one-way valve 6 a provided thereon to permit fuel to enter the tank but not filler neck 4 a .
  • the tank has a float operated vent valve 7 a provided in the top thereof and registered thereagainst by flange 8 a with the valve 7 a extending through an access opening into the tank for sensing the fuel level indicated generally at 14 a.
  • Valve 7 a has conduit 9 a connected thereto and to storage canister 10 a which is vented through the atmospheric air inlet tube 12 a .
  • Canister 10 a has a purge line 11 a connected thereto and adapted for connection to the air (not shown) of the vehicle engine.
  • Tube 9 a is also connected through conduit 13 a to the enlarged upper end 5 a of the filler neck for recirculating fuel vapor thereto.
  • the aspirating effects of the liquid fuel flow from the nozzle creates a reduced pressure in the upper end of the tube 5 a and draws in air and vapor from 13 a into the filler tube 4 a and the tank.
  • the air drawn in further increases fuel vaporization. Flow of fuel vapor to the atmosphere through tube 13 a can occur if 13 a vapor flow is not significantly limited.
  • the present invention provides a solution to the above-described problem of minimizing the vapor storage capacity of a fuel vapor storage canister in a fuel vapor vent control system particularly for a motor vehicle and more particularly during refueling operations.
  • the system of the present invention employs a float operated vent valve mounted in the top of the fuel tank with the vent valve outlet connected through a vent line to a storage canister which is adapted for purging and vapor flow into the air inlet of an engine upon engine startup.
  • the filler neck of the tank has the upper end enlarged to receive a fuel filler nozzle therein and includes a seal for sealing about the nozzle upon insertion.
  • a recirculation line is connected from the filler neck at a location downstream of the nozzle seal to the vapor line connected to the canister.
  • FIG. 1 is a pictorial schematic of the invention fuel vapor vent system for a motor vehicle fuel tank during refueling
  • FIG. 2 is an enlarged view of a portion of FIG. 1;
  • FIG. 3 is a view similar to FIG. 1 for a prior art system
  • FIG. 4 is an enlarged view of a portion of FIG. 3;
  • FIG. 5 is a pictorial schematic of another prior art system.
  • the system of the present invention is indicated generally at 20 and includes a vehicle fuel tank 22 having a filler neck 24 attached thereto with an enlarged upper end 26 with a refueling filler nozzle 28 received therein for providing flow of fuel indicated by the black arrows into the interior of the tank.
  • the fuel level in the tank is indicated generally at 30 .
  • the enlarged portion of the filler neck 26 has disposed therein a mechanical seal 32 which seals about the outer periphery of the nozzle 28 and preferably includes an annular member of elastomeric material as shown in FIG. 2.
  • the enlarged portion of the filler neck 26 also has a pressure relief valve 34 disposed therein for providing bypass of the seal 32 in the event of nozzle shutoff failure and excessive fuel pressure buildup within the filler neck.
  • a pressure relief valve 34 disposed therein for providing bypass of the seal 32 in the event of nozzle shutoff failure and excessive fuel pressure buildup within the filler neck.
  • Below the seal 32 is disposed an optional one-way flapper valve 36 which is opened by the nozzle 28 upon insertion through the seal 32 as shown in dashed outline in FIG. 2.
  • the tank 22 has a float operated vent valve 38 disposed in the top wall thereof through an access opening and has a flange 40 thereon registered against the exterior surface of the tank top for attachment thereto and sealing there around in a manner well known in the art.
  • the outlet of the valve 40 is connected through a conduit 42 to the inlet of a vapor storage canister 44 which has a purge line 46 connected thereto which is adapted for connection to the air inlet of an engine (not shown) for enabling flow of vapor therethrough upon engine startup.
  • An atmospheric air inlet 48 is provided in the canister to provide purge flow of air into the canister upon engine startup.
  • a vapor recirculation line 50 has one end connected to the upper end 26 of the filler neck in a region below or downstream of the mechanical seal 32 ; and, the opposite end of the line 50 is connected into the vapor purge line 42 for providing recirculation of a portion of the vapor flowing through the line 42 . This recirculation is facilitated by the aspiration effect of the flow of the fuel in the filler neck 24 during refueling.
  • the present invention thus provides a conduit from the canister vent line for recirculation through the filler neck fuel vapors in the tank during refueling and provides a mechanical seal above the recirculation conduit and a liquid seal in the filler neck upon insertion of a refueling nozzle and fuel flow into the filler neck.
  • the system of the invention minimizes the flow to the storage canister during refueling and thus reduces the quantity of vapor the canister must store and permits reducing the canister adsorbent fill and overall canister volume.
